摘要： The present invention is based on the discovery of polymorphisms (SNPs) in the penicillin binding protein (pbp3) gene in Staphylococcus aureus. The presence of G88A and/or G2047A SNPs provides an accurate, reliable biomarker for the presence of Methicillin Resistant Staphylococcus aureus (MRSA), specifically the community-associated MRSA (CA-MRSA). The present invention provides reagents used for detecting the SNPs as well as methods of identifying and using these variants to screen subjects for presence of CA-MRSA. The methods involve isolating a biological sample from a mammal (preferably a human) and testing for the presence of a SNP in the pbp3 gene which is associated with CA-MRSA.

摘要： The present invention relates to an antibiotic resistance profile for Neisseria gonorrhoeae by assessing the presence of mutations (e.g., SNP) in antibiotic resistant genes that confer bacterial resistance against antibiotics such as penicillin, tetracycline, fluoroquinolones, cephalosporin, macrolides and spectinomycin. There is provided a method and a kit for generating an antibiotic resistance profile for Neisseria gonorrhoeae by utilizing a multiplex PCR to amplify segments of antibiotic-resistant genes, allele-specific primer extension to detect gene mutation, and detection of such gene mutations with gel electrophoresis, capillary electrophoresis, or DNA microarray. The present method provides useful information to physicians relating the antibiotic susceptibility of Neisseria gonorrhoeae against different classes of antibiotics. Relying on this personalized diagnostic tool, physicians can better inform about antibiotic susceptibility and thereby open up medical intervention avenues for treating Neisseria gonorrhoeae with antibiotics. There is provided a therapeutic application of the antibiotic resistance profile that has advantages of: (i) providing a more effective regime for gonorrhea treatment; and (ii) halting the evolutionary pressures towards antibiotic resistance in the Neisseria gonorrhoeae therapy.

摘要： There is disclosed a method for determining azole resistance in Candida glabrata. A biological sample containing Candida glabrata is obtained and a normalized mRNA level of CDR1 gene is determined using qRT-PCR. Using a microbroth dilution assay conducted at azole concentrations of about 2-8 μg/mL, a susceptible isolate of Candida glabrata is obtained. A qRT-PCR assay is employed on the susceptible isolate and an average mRNA level of CDR1 is obtained. A fold-change value for CDR1 is obtained by comparing the CDR1 mRNA level of the biological sample with that of the average mRNA level. A ≧2-fold change value is indicative of an azole resistance in Candida glabrata. The present method provides a qRT-PCR assay for azole resistance that has a sensitivity of ≧90% and a specificity of ≧90%.
